The price of a student citizen ticket to the fall musical is $4

Step-by-step explanation:

C = the price of a senior citizen ticket to the fall musical

S = the price of a student citizen ticket to the fall musical

Day 1:

6C + 5S = 50

Day 2:

8C + 1S = 44

Manipulate the equations so that they have a common coefficient.

Multiple Day 2's equation by 5.

8C + 1S = 44

40C + 5S = 220

Subtract Day 2's equation from Day 1's

(40C + 5S = 220) - (6C + 5S = 50)

(40C + 5S) - (6C + 5S) = 220 - 50

(40C - 6C) + (5S - 5S) = 220 - 50

34C = 170

C = 5

Substitute C into either equation to solve for S.

Day 1:

6C + 5S = 50

6(5) + 5S = 50

30 + 5S = 50

5S = 50 - 30

5S = 20

S = 4

Day 2:

8C + 1S = 44

8(5) + 1S = 44

40 + 1S = 44

1S = 44 - 40

S = 4

3y = -8x -27

Solution :

A line equation is an algebraic way of expressing the collection of points that make up a line in a coordinate system. The many points that collectively make up a line on the coordinate axis are represented as a group of variables (x, y) to create an algebraic equation, also known as an equation of a line.

Given line: 3x - 8y = -7

-8y = -7 -3x

y=- (-7 -3x)/8

y= 7+3x/8

So, the slope (m1) = 3/8

Let’s consider the slope of the line perpendicular to the given line as m2

Then, m1 x m2 = -1

3/8 x m2 = -1

m2 = -8/3

Now,

The equation of the line perpendicular to the given line and passing through the point (-3, -3) will be

y – y1 = m (x – x1)

y – (-3) = -(8/3) (x – (-3))

y + 3 = (-8/3) (x +3)

3y + 3 = - 8x - 24

3y = -8x -24-3

3y = -8x -27

Thus, the equation of the required line is 3y = -8x -27

Correct answer is B. Fred Korematsu was arrested for Refusing to move to the detention center.

Fred Korematsu is detained on May 30, 1942, in San Leandro, California, for defying President Franklin Roosevelt's contentious Executive Order 9066, which called for the internment of almost all Japanese Americans in the US following Japan's assault on Pearl Harbor.

Korematsu, who was 23 at the time, sued in federal court after being found guilty and being imprisoned in a Utah camp. The U.S. Supreme Court ultimately heard his case, and in 1944 it affirmed the government's argument that the detention was necessary due to "military necessity."

However, a federal court overturned Korematsu's sentence for escape internment in 1983, declaring that he had been the victim of a "grave injustice."

Answer: 8 – (2 + 1) × (5 – 3) = 2

Step-by-step explanation:

8 – 2 + 1 × 5 – 3 = 2

8 – 2 + 1 × 5 – 3 = 2      ==> notice there is an '8-' in the equation, Let's solve for the difference between 8 and 2.

8 – (2 + 1 × 5 – 3)+(2 + 1 × 5 – 3) = 2 + (2 + 1 × 5 – 3)

8=2 + (2 + 1 × 5 – 3)

8-2=2-2+(2 + 1 × 5 – 3)

6=2 + 1 × 5 – 3   ==> 6 is a multiple of 2 and 3. Let's see how we can convert 2 + 1 × 5 – 3 into the product of 2 and 3

6=(2 + 1) × (5 – 3)

6=3 × 2

6=6√  ==> since this is right, let's substitute the parentheses to the original equation

8 – 2 + 1 × 5 – 3 = 2    ==> 8 – (2 + 1) × (5 – 3) = 2

The value of machine after 3 years which costs $25000 will be $17500.

What is the depreciation in value ?

An asset loses value over time as a result of use, damage, or obsolescence. This decline in value is known as depreciation.

The value of a machine is $25000.

The value of the machine after 3 years must be found.

Let y be the machine's price and x be its production time.

We are aware that the line's equation is y = mx + c.

Machine costs $25,000, therefore the point is (0,25000), and when it costs nothing after 10 years, the point becomes (10,0).

Regarding the first point (0 , 25000)

25000 = 0(x) + c

c = 25000

For a second point which is (10,0)

0 = 10(m) + 25000

m = -2500

As a result, y = -2500x + 25000 is the equation.

We know that , we have to find the value of machine after 3 years i.e., x = 3.

So ,

y = - 2500 × 3 + 25000

y = -7500 + 25000

y = $ 17500

Therefore , the value of machine after 3 years which costs $25000 will be $17500.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign. Equation, statement of equality between two expressions consisting of variables and/or numbers.

Given:

A $25,000 machine depreciates linearly to 0 over a 10 year period.

According to given question we have

At the time of launch, its cost is $25,000 so the point becomes (0,25000) and after 10 years its cost becomes zero then the point becomes (10,0).

For the first point (0, 25000)

25000 = 0(x) + c

c = 25000

For second point (10,0)

0 = 10(m) + 25000

m = -2500

Thus the equation become y = -2500x + 25000.

When x=3

y = -2500x + 25000

y=-2500*3+25000

Step-by-step explanation:

Starting from the x-value (A column) for -7 and going down the y-values values (B column) are 5, 4, 3, 2, 1, 0, 1, 2

The function is given to us in the B column. We can use this to find the y-values without having to plug them in each time.

Finding the Vertex

In absolute value functions, there is a vertex. The vertex, in this case, is the minimum where the y-values change from decreasing to increasing. The absolute value formula is y = a|x - h| + k.

The vertex is equal to (h,k). The h-value in the function above is -2 and the k-value is 0. Thus, the vertex is at (-2,0).

Finding Slope

The slope of an absolute value function is written before the x. Since there isn't anything before the x in this function, the slope must be 1. So, the values either increase or decrease by 1.

Like all positive absolute value functions, the graph will decrease, reach 0, then begin to increase. The graph will reach 0 at the vertex.

Writing Out the Values

The table shows us that the y-values begin at 6. Then, we decrease by one until we get to 0.

Each of these x-values matches up with one of the y-values. Then, the graph begins to increase once again.

So together the y-values for the x-values -8 through 0 are 6, 5, 4, 3, 2, 1, 0, 1, 2.

a) There is 2.54 quarts in the resulting mixture (b) The percentage of the resulting mixture is  50.8% antifreeze.

Percentage is defined as parts per hundred. Percentage is calculated by dividing the given amount by the total amount and multiplying by 100.

a) 18% of 3 quarts antifreeze contains (18/100) × 3 quarts of antifreeze.

amount of antifreeze = 0 .18 × 3 = 0.54 quarts

Now to this solution 2 quarts of antifreeze is added.

Therefore total amount of antifreeze in the resulting mixture = 2 + 0.54 = 2.54 quarts.

b) Total amount of the resulting mixture = 2 + 3 = 5 quarts

amount of antifreeze in the mixture = 2.54 quarts

Percentage antifreeze in the mixture = (2.54 / 5) × 100 % = 50.8 % .

Therefore there is 2.54 quarts of antifreeze in the mixture and its percentage is  50.8% of the total mixture.

Compounded Quartely means 4 times per year

A = P(1 + r/n)^nt

A= 13000(1 + 0.04/4)^4(7)

A = 13000(1 + 0.01)^28

A = 13000(1.01)^28

Answer: Equation for the line that passes through the points (6,-5) and (-4,1) is equal to 3x+5y+7 = 0.

Step-by-step explanation:

The equation of a line can be written in slope intercept form:  

y = mx + b   where m is the slope and b is the y-intercept

You can use the two points to find the slope m:

m = (y2 - y1 ) / ( x2 - x1 )

Given that points (6,-5) and (-4,1)

It represents the values are,

x1 = 6

y1 = -5

x2 = -4

y2 = 1

so,

Replace with x1, x2, y1, y2 values in this equation,

we can write,

m=(1-(-5)) / (-4-(6))

m = (1+5) / (-4-6)

m= 6/-10

m = 3/-5

Now you can select either point and substitute the coordinates in the equation to determine b, the y intercept.  Let's us (-4, 1):

y= mx + b

so, x = -4 and y = 1 and m = 3/-5

Replace with the values in this equation,

y= mx +b

1 = (-3/5)(-4) + b

1 = (0.6)(4) +b

1 = 2.4 +b

1-2.4 = b

-1.4 = b

b = -1.4

The equation will be:

y = mx +b

substitute m and b values,

Then,

y = (-3/5)x + (-1.4)

y = (-3/5)x -1.4

In standard form, the equation would be transformed as:

y = (-3x-7) / 5

5y = -3x-7

3x+5y = -7

3x+5y+7 = 0

In standard form, the equation would be transformed as: 3x+5y+7 = 0

Therefore,

Equation for the line that passes through the points (6,-5) and (-4,1) is equal to 3x+5y+7 = 0.
